Group 1 - Capacitors are critical components in electronic circuits, serving functions such as energy storage, filtering, and coupling, with significant differences in internal structures based on type, and some contain valuable precious metals in their manufacturing materials [1] - The distribution and content of precious metals vary among different types of capacitors; for instance, electrolytic capacitors often use ruthenium plating for the anode, enhancing corrosion resistance and stability, while ceramic capacitors may use silver paste and occasionally gold for improved conductivity and oxidation resistance [3] - High-voltage capacitors require higher reliability and pressure resistance in electrode materials, often utilizing high-purity silver or silver plating, ensuring stable operation under high pressure due to silver's excellent conductivity and thermal stability [5] Group 2 - The value of capacitors containing precious metals is primarily determined by the specific content of these metals, and recovery involves classification, disassembly, and chemical analysis to accurately measure metal weight proportions [6] - A systematic evaluation and processing workflow is necessary for the recovery of capacitors containing precious metals, including precise classification, extraction, and assessment of precious metal content, along with calculations of recovery value based on current metal market prices and processing costs [8]
